Title: An improved method of controlling a straight-bar knitting machine
IPC: D04B15/99
Filed: 1959-06-11
Abstract: 892,072. Knitting-machines. MONK (SUTTON IN ASHFIELD) Ltd., S. A., and MONK, S. A. Sept. 8, 1960 [June 11, 1959], No. 19960/59. Drawings to Specification. Class 74 (2). Electrical relay-operated switches are provided instead of the cams used in Specification 865,364 to determine the number of courses between each fashioning course. The selector switches used for determining the fashioning courses are selectively coupled to the relayoperated switches which correspond in number to the maximum number of courses between fashioning courses. The desired number of courses having been determined, after the corresponding number of relay switches have been operated the selector switch operates a solenoid to close a switch which energizes the solenoid which moves the cam-shaft to effect a fashioning motion. The movement of the cam-shaft opens a switch in the circuit of the relay-operated switches to open and reset the latter.
Patent GB-743583-A (GB)
Title: Manufacture of new cobaltiferous monoazo-dyestuffs
IPC: C09B45/20
Filed: 1952-08-07
Abstract: Dyestuff intermediates containing methylsulphonyl groups are made by methylating the appropriate sulphinic acids or oxidizing the corresponding methylthio compounds.  Thus o-nitro-chlorobenzenesulphonyl chlorides are reduced to the sulphinic acids, methylated, treated with caustic alkali to replace the nuclear chlorine atom by hydroxyl and the nitro group finally reduced to amino.  Aminophenyl methyl sulphones can further be condensed with diketene or b -keto-esters to give acylacetic arylides, or the amino group can be converted to hydrazino and condensed with b -keto-esters to form pyrazolones. Also, O - acyl - sulphonyl derivatives of naphthol-sulphonic acids can be converted successively into sulphonyl chlorides, sulphinic acids and methyl sulphones and the O-acyl group then hydrolysed off.  An example is given of the reduction of benzoxazolone-5-sulphonyl chloride to the sulphinic acid, methylation to the 5-methyl sulphone and hydrolysis of the latter to give 2-amino-5-methylsulphonylphenol.  Other products of the above types are mentioned.ALSO:The invention comprises cobaltiferous azo dyes containing less than one metal atom per dyestuff molecule, the latter being of the formula HO-R1-N=-R2-OH in which the hydroxyl groups are bound to the residues R1 and R2 ortho to the azo linkage and one of the residues contains an aromatically - bound methyl sulphone group; R1 is a benzene residue and R2 represents a coupling component containing an aromatic residue, both being free from sulphonic acid and carboxylic acid groups.  There may be two such dyestuffs bound to the cobalt atom. The metalliferous dyestuffs may be made by metallizing the monoazo dyestuffs or mixtures thereof with 1/2 to 1 atom of metal per dyestuff molecule and/or carrying out the process in a weakly acid or alkaline medium.  Suitable metallizing agents are cobalt hydroxide, sulphate or acetate or complex cobal derivatives of aliphatic dicarboxylic or oxycarboxylic acids.  There may be present bases, salts of organic acids or organic solvents.  The metal-free starting materials are made by coupling diazotized o-aminophenols with suitable coupling components such as phenols, naphthols, oxyquinolines, aceto-acetic arylides, 1-aryl-pyrazolones and pyrazolone-3-carboxylic acid arylides. They need not be separated from the coupling mixture before metallization.  The products of the invention can be used for dyeing and printing silk, leather, wool and superpolyamides or superpolyurethanes from neutral, weakly acid or weakly alkaline baths.  Examples show the formation and metallization of the following dyestuffs:-2 - amino - 4 - methylsulphonylphenol --> 1-phenyl-3-methyl-5-pyrazolone, 2 - amino - 4-methyl - sulphonylphenol --> 1 - acetylamino-7-naphthol and 4-nitro-2-aminophenol --> - (m - methylsulphonylphenyl) 3-methyl-5-pyrazolone.  A further example describes the dyeing of wool yellow with the first-named product from an acetic acid bath. Tables are given of other dyestuffs that can be metallized and other suitable components are mentioned.

Title: Improvements in methods of making ice and apparatus therefor
Inventor: GREEN JUNIOR CHARLES M
IPC: F25C5/06
Filed: 1954-07-12
Abstract: 750,576. Ice-making. TAYLOR, F. W. July 12, 1954, No. 20289/54. Class 29. Ice making apparatus comprises a container 1 for the liquid to be frozen and one or more fluidtight chambers 14 immersed in the liquid, each chamber having a flexible, deformable wall 18 which is in heat exchange contact with a refrigerant coil 9<SP>1</SP> within the chamber. Ice forms in a layer on the wall 17 and then the wall is deformed by the application to or the withdrawal from the chamber of fluid pressure so that the ice layer separates in part from the wall. Liquid then flows into the space between the wall and the frozen layer and freezes, and the wall is again deformed and so on. Ultimately the ice sheets break away from the walls. The top and bottom of the chambers have electric or other heaters 26 to confine the ice to the flexible walls. Each chamber may, as shown, be divided by a partition to form two parts 23, 23<SP>1</SP> which can be connected to the fluid pressure source and which each have a flexible wall 17. Alternatively the chambers need not be partitioned and have each two opposite walls 17. As shown, the detached ice floats to the surface and is removed by a conveyer 7. The supply of fluid pressure and hence the ice-making operation can be controlled by an electric timer, the control circuits being fully described with reference to Fig. 6 (not shown). In modifications, the chambers may be disposed on the walls of the container or the ice may be allowed to accumulate until a block of ice is formed. In this case the flexible walls may slope to allow easy withdrawal of the block. Small blocks of ice may be cooled to a temperature below the freezing point of water, then wetted with water and joined together in a press. The blocks may have concave faces so that, when stored, they have line contact one with another and do not fuse together.
